Question

What steps can be taken to control soil erosion in the hilly areas for 3 marks?

Answer 1

The following steps can be taken to control soil erosion in the hilly areas:
a ) Ploughing along the contour lines can decelerate the flow of water down the slopes . This is called contour ploughing.
b ) Steps can be cut out on the slopes making terraces. Terrace Cultivation restricts erosion.
c ) Large fields can be divided into strips. Strips of grass are left to grow between the crops . This breaks up the force of the wind. This method is known as strip cropping .
d) Planting lines of trees to create shelter also works in a similar way . These shelterbelts have contributed significantly to the stabilisation of sand dunes and in stabilising the desert in western India .
